' Application May c, 1946, Serial No. 667,720

The invention relates to equipment for distribution of materials by the application of pressure.

In many instances'it is desirable to discharge I materials either in liquid or powder form by means of a suitable carrier. Some instances being the spraying of insecticides, paints, and various types of chemical distributions; g y

It is one of the objects of the present invention to provide a'plurality of containers which the gaseous fluid contents thereof to the discharging container to facilitate such discharge. It ist-also one of the objects of the invention to provide a pair of containers which are alternately filled and discharged, and where such containers are interconnected so that the incoming liquid in one container increases the pressure in theother; r p Still another object of the invention isto provide a pair of containers wherein the gaseous medium normally in the containers will be transferred from one to the other as the containers are alternately filled and discharged.

It is an object of the invention to provide a pair of interconnected vessels where each vessel is arranged to receive a charge of material to be discharged, and each is arranged to have a carrier liquid injected thereinto so that one vessel may discharge while the other is being filled, and wherein further the gaseous fluid from the vessel being filled will be transferred to the vessel being discharged so as to constantly agitate the mix of carrier liquid and material.

Still another object of the invention is to provide a pair of vessels for mixing materials and carrier liquids in such a manner that the vessel being filled will transfer the air therefrom to agitate the mix in the other vessel as it is discharged.

A still further object of the invention is to provide a pair of vessels which may be alternately filled and discharged, pressure from the incoming liquid filling one vessel and effecting agitation of the liquid in the other vessel which is being emptied.

Still another object is to provide a plurality of 2 Claims. (Cl. 259-60) containers whereby each may be independently operated to agitate and discharge a liquid therefrom when the pressure therein is increased by an independent source.

Another object is to provide a container to simultaneously agitate and discharge materials wherein the medium used to discharge the material from the container is also used to agitate the material being discharged.

Other and further objects of the invention will be readily apparent when the following description is considered in connection with the accompanying drawings wherein: I

Fig. 1 is a side elevation ,ofapair of containers interconnected for use in practicing" the invention;

Fig. 2 is a top plan view looking down on the assembly of Fig. 1 and illustrating'a section on the line 22 of Fig. 1. a i v T In the mixing and discharge of materials such as insecticide, pairltsand chemicals, it is almost impossible to effect proper mixing by a continuous procedure and the present invention directs itself to a batch mixing apparatus wherein one vessel or container such as the tank 2 is filled with a carrier liquid through the inlet pipe 3. Such liquid may be water or anysuitable liquid carrier which is arranged to be mixed with a chargeof material introduced through the opening 4 into the tank.

Of necessity there will be some mixing of the material which is to be distributed and the carrier liquid entering the tank, but it is desirable that additional agitation be accomplished. To this end the tank 2 has a connecting pipe I leading into the second tank 8, and the pipe I is shown as terminating in a perforated distributor coil 9 adjacent the bottom of the tank or vessel 8. It seems obvious that, as the liquid enters the vessel 2, any air or gaseous fluid in the top thereof will be forced through the pipe to escape through the distributor coil 9 in the vessel 8. In actual practice the vessel 8 will have previously been filled .with a suitable material and the carrier liquid and the same will be discharging from the same pipe 3 that afforded inlet of the carrier liquid, in view of the fact that the distributor coil 9 is adjacent the base of the vessel. It seems obvious that the mere filling of the tank 2 will effect agitation of the carrier liquid and material in the tank 8. This transfer of the air of gaseous fluid from tank 2 to the tank 8 assists in maintaining a discharging pressure on the tank 8 while the tank 2 is being filled.

When the tank 8 has discharged its contents then the introduction will be reversed so as to move into the tank 8, and the outlet from the tank 2 will be opened to arrange for the discharge of the contents thereof. As the tank 8 is filled the gaseous fluid will move outwardly from the upper end thereof through a pipe f2 and into the distributor pipe l3 and perforated distributor coil M in the base of the tank 2.

Suitable pressure gauges l6 and cover members I! for the openings 4 can be provided. The valve l9 can be arranged in each of the covers to permit the exhaust of any excess pressure in the tank. Transfer or connecting pipe I and 12 will ance the vessels and effect transfer of the gas-' eous fluid in the desired direction and'through the proper perforated distributor coil. A sight gauge 2'5 may be provided on each tank to indicate the volume of liquid therein. It seems Jobvious that each vessel {may be operated independently to agitate and discharge ;material therefrom by passing compressed air from the compressor such as 21 through a pi e 28 into distributor ring pipe I. i

Fig. 2 shows the compressor 21 asbeing of any desired type including a source of power and a compressors This structure may or may not be used and can be employed to supplement the pressure in the containers to speed up the accumulation'ofthe desired pressure for use of the devices. =With the arrangement just described, it seems clear that-analternate filling and discharging and mixing of the liquids and materials will be accomplished. -It seems obvious that any suitable material may be introduced in the'opening '4 and this may be in either liquid, solid or powder form,

.andin some instances two liquids may be blended alternate filling and discharging of the vessels or tanks in such amanner that the filling of one effects and maintains a discharging pressure on the other tank while also causing the agitation of the contents of such discharging tank. Only one distributor coil has been shown in the drawing; however, it is intended that "any number may be used.

It is further intended that each container may be operated independently to agitate and discharge a material therefrom and a compressor 21 may be applied to each container if desired.

The invention claimed is:

1. An assembly for discharging materials comprising a pair of containers, means to alternately charge said containers with a material to be carried, means to thereafter alternately charge said containers with a carrierliquid, a pair of conduits connecting the top of each of said containers to adjacent the base of the other container so that the introduction of carrier liquid into one container displaces gaseous fluid from such container into the other container to increase the pressure therein, said liquid charging means being connected to discharge the mixture of carrier liquid and material, said connecting means including a perforated distributor coil in each vessel disposed to effect mixing of the liquid and the material by. the gaseous fluid being transferred 1. a

2. A combination charging, mixing and discharge apparatus comprising a plurality of vessels, means to introduce a material into each of said vessels, a connection for the introduction and discharge of liquid for each vessel, means interconnecting the top of each of said vessels to the interior of the base or the other vessel so that the entrance of liquid to one vessel discharges any gaseous fluid therefrom to the, base of the other vessel to increase the pressure in such other vessel sothat such increased pressure in turn serves to effect discharge of themixed carrier liquid and materialtherefrom, and simultaneously effect agitation .to said mixed carrier liquid and material therein 7 i THOMAS E.
